  Design, Synthesis, and Evaluation of Aza-Peptide Epoxides as Selective and Potent Inhibitors of Caspases-1, -3, -6, and -8

  摘要：

  Aza-peptide epoxides, a novel class of irreversible protease inhibitors, are specific for the clan CD cysteine proteases. Aza-peptide epoxides with an aza-Asp residue at PI are excellent irreversible inhibitors of caspases-1, -3, -6, and -8 with second-order inhibition rates up to 1910 000 M-1 s(-1). In general, the order of reactivity of aza-peptide epoxides is S'S > R,R > trans > cis. Interestingly, some of the R,R epoxides while being less potent are actually more selective than the S,S epoxides. Our aza-peptide epoxides designed For caspases are stable, potent, and specific inhibitors, as they show little to no inhibition of other proteases such as the aspartyl proteases porcine pepsin, human cathepsin D, plasmepsin 2 from P. falciparum, HIV-1 protease, and the secreted aspartic proteinase 2 (SAP-2) from Candida albicans; the serine proteases granzyme B and alpha-chymotrypsin; and the cysteine proteases cathepsin B and papain (clan CA), and legumain (clan CD).
